Don’t go overboard with rich moisturizers. While you want to keep your skin supple during summer, you can afford to lighten up—especially since thick doesn’t necessarily equal better. Heavy creams can create a barrier on the surface of your face and keep your skin from absorbing moisture. And formulas that contain synthetic ingredients can trap dead cells and leave your complexion looking dull.
Do use a nighttime face lotion. There’s evidence that skin-cell regeneration is slightly faster at night than during the day, so take advantage of your skin’s receptiveness and don’t skimp on overnight hydration.
